Attaching The Flash Unit - Leica M Monochrom Anleitung

ATTACHING THE FLASH UNIT

Before attaching a flash unit to the accessory shoe on the camera,
– the cover that protects the accessory shoe and the socket when
not in use, must be detached to the rear, and
– the camera and flash unit must be turned off.
When attaching a flash unit, you should ensure that the foot of the
flash unit is fully inserted into the accessory shoe and the clamping
nut is tightened to prevent it accidentally falling out. This is
particularly important for flash units with additional control and
signal contacts, because if the position in the accessory shoe
changes the necessary contacts can be broken, leading to
malfunctions.
Notes:
• This also applies when using a flash unit with SCA adapter set
(see p. 220).
• Make sure the accessory shoe cover is always attached when no
accessories are in use (such as a flash unit, an external
viewfinder or microphone). It will protect the socket 28 for a
time against water incursion.
FLASH MODE
Fully automatic flash mode, i.e. controlled by the camera, is
available on the camera with the system-compatible flash units
listed in the previous section, and in aperture priority
exposure modes.
In addition, automatic illumination control is operational in all three
exposure modes. This means that in order to ensure a balanced
relationship between flash and other lighting at all times, the flash
power is reduced by up to 1 /

compatible flash unit will not be fired in aperture priority mode. In
such cases the shutter speed is governed by the ambient
brightness and is shown in the viewfinder.
In aperture priority mode A and with manual setting, the camera
also allows the use of creative flash techniques such as synchroni-
zation of flash firing with the 2nd shutter curtain rather than the
1st, as is usual, and flash with slower shutter speeds than the sync
speed of / s. These functions are set on the camera using the

menu (for more details, refer to the relevant sections below).
In addition, the camera transfers the set sensitivity to the flash
unit. Provided it has received such information and the aperture
manually set on the lens is also input to the flash unit, this allows
the flash unit to automatically adjust its range values accordingly.
The sensitivity setting cannot be influenced from the flash unit as it
is transferred from the camera.
